MPO-IN-1 (C007B-374583)

MPO-IN-1 is a potent, orally active, and irreversible indole-containing inhibitor of myeloperoxidase ( MPO ). MPO-IN-1 has IC 50 s of 2.6 μM and 5.3 μM for MPO and thyroid peroxidase (TPO), respectively. MPO-IN-1 inhibits MPO activity in an acute mouse model of inflammationIn VivoMPO-IN-1 (compound 2) (5 and 90 mg/kg; p.o.; four hours post-Zymosan A administration) significantly reduces MPO activity in a mouse peritonitis model of acute inflammation .
